Watch Repair Tool BERGEON [Bergeon] Aluminum Ring Eyeglass Loupe 2.5 degrees (4.0x) BE7913-2.5 Purchased on Amazon in June 2021. Usage frequency is not high. It's a type that attaches to eyeglasses, but I used it as a handheld loupe without using the clip. The magnification is just right for viewing watch dials and movements. There are no scratches or scuffs on the lens. The body is also clean, but it is a used item, so please understand before purchasing.
